oolvzonnsiive APPARATUS To all whom it may concern:

Be it known that I, OSCAR P Os'rnnennn, a citizen of the 'United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful improvements in Condensing Apparatus, of Which the following is a specification.

invention relates to improvements in I condensing apparatus, the object of the invention being to provlde an mproved" apparatus in which steam is condensed by di-- rectcontactwith a shower of cooling Water in a system Which is maintained automatically under the desired vacuum, andvvh'ich utilizes a cooling agent for'reducing the temperature of the 'water. I

A. further object is to provide an eflici'en't condensing apparatus for povveror indusprevent the introduction into the condenser of the gases usually carried by the injection water. k

Afurther object is to provide a compact and efficient counter-current cooling appa- "ratus wherein the intermediate body of Water is cooled by the external body, and insure the perfect interchange of heat as'a maximum of radiating surface is provided Within a relatively small space.

A further object is to provide improved means for automatically controlling the pressure or vacuum in the system, and to provide automatic 'means for supplying Water to make up for deficienciesin thesystem due to loss.

With these and other ob ects in new, the invention consists in certain novel features of construction and combinations and'ar rangements of parts as will be more fully hereinafter described and pointed'out infthe I claims. 3

is avievv in elevation partly in section illustrating my improvements. Fig. 2 is a frag- Figqil "is a view in longitudinal section through the condensing chamber and the counter-current apparatus, and Fig. '5 is a TVIGW lnsectlon on the line 55 of Fig. 4.

ends with partitions 8, dividing the same i into a relatively long intermediate chamber {1 and relatively short end chambers 5.

A plurality of tubes 6 extend through the partitions 3, and connect the end chambers 5, While a horizontal partition 7 extends through one, of the partitions 3, dividing one end chamber?) into an upper and lower compartment, and this partition 7 extends to a point adjacent the other partition 3 for a purpose Which will hereinafterappear.

My improved condenser per 86, 8, is supported upon the counter-current cooling apparatus 1, and at its lower restricted end 9 communicates with the top of the countercurrent coolinQapparatus as clearly shown in Figs. 4: and 5. in its upper end with an annular Water Condenser 8 is provided chamber 10 having a perforated bottom 11 through which the Water falls in a spray upon baiiles 12 and 13 before it enters the a lower end 9 of the condenser.

, 14 represents a steam inlet which discharges into the condenser below the baffle "13,and as this steam rises, it contacts with the falling shower or spray and is condensed, the Water accumulating in the condenser being drawn off by a pump 15 through a pipe 16, and discharged through a pipe 17 to a hot Water tank or directly to the boiler. v

The level of Water in the condenser is controlled by a fioat valve 18 in a valve casing 19 communicating at its lower end With pipe 16, and at its upper end connected by a pipe 20 With the condenser 8. The floatvalve 18 controls the supply of Water from an inlet pipe /21, and the position of the float valve is controlled by the levelof liquid in the condenser. I I y e v. I Itis of course to be understood that, the

iio i carryiofl thewater asit condenses from the steam, but in case there is a discrepancy, the difference will .be made up by water which denser by a pipe 23, and this airand gas is designed to be discharged into the atmosphere by said pump 22. w

An engine 2% is adapted to drlve both the pumps 15 and 22. l p 25represents a water pipe whlchconnects the bottom of the counter-current cooling apparatus 1 with the top of the condenser 8,

the endsof this pipe 25, a pump 26 is located and. ope ates to force a continuous fiow'o f water from the bottom of the countencurrent cooling apparatusto the top of the con- 'denser, so that a uniform spray may be'had through the condenser at all times. a

The water in the counter-current cooling apparatus is cooled by Water which is drawn from a source of supply 27 through a pipe 28between the ends of which latter, a pump 29 is provided. Water from the pipe 28 enters the lower compartment of chamber 5,- then flows through the lower set of tubes 6 to the other chamberb, thence through the upper set of tubes t to the upper compartment of the first-mentioned chamber 5, and thence through an outlet pipe 30 to a receptacle 31 to receive the same. The water of condensation therefore gives up its heat to the cooling agent, and the latter has a continuous flow through the chambers and tubes as above explained, so that a large heat transmitting surface is had. This is particularly true as the water from the condenser is compelled to pass around the par- 7 tition 7 and in its journey through the counter-current cooling apparatus will have its temperature reduced, so that when at its lowest temperature, it will be discharged into chamber 10 and contact with the steam, hence the highest temperature of liquid will be in the lower reduced end 9 of the condenser, and the lowest temperature of water will be in the upper chamber 10.

. 32 represents an engine which drives both pumps 26 and 29, and 33 is a steam pipe which supplies steam to this engine 32 and also to the engine 24 above referred to. The passage of steam to both of these engines is controlled by a barometric governor 34 which consists of a vertical column connectedat its upper end by a pipe 35 with the condenser 8, and at its lower end communioperation of a valve 38 in the steam pipe 33 i if? and the position of this float is controlled by the mercury in'the column and in the lower end of the chamber 36. If the vacuum falls scope of the appended claimsand discharges into chamberlO. Between I claim as new and desire to secure by Letin the condenser, the mercury will accumulate in the lower end of the chamber 36, causmg the float to risev and causing the valve 38 to open wider, which will compel the general form and arrangement of parts described without departing from my invention, and hencel do not limit myself to the precise details set forth, but consider myselfat liberty to make such changes and alterations as fairly fall within the spirit and Having'thus described my invention,\vl1at ters Patent is: r V
